The Portable One offers a complete, easy to use audio test set housed in a rugged case ready for almost anything. With twelve different measurement functions selectable at the push of a button, Portable One is comprehensive while remaining user-friendly. Its popularity is no less due to its outstanding performance specifications; yet Portable One is as affordable as lower-performing test sets.

Portable One Plus Access includes comprehensive analog generation and measurement, with two outputs and two inputs. Easy-to-set-up sweep capability produces graphs of frequency response, distortion vs. frequency and even amplitude sweeps. Non-volatile storage of up to 30 tests allows easy one-button recall of your favorite test setup. Connect Portable One to a compatible printer and produce reports incorporating high-resolution graphs.
